1. A method of wireless communication performed by a first sidelink user equipment (UE), comprising:
detecting a first sidelink transmission in a channel occupancy time (COT), the COT for sharing with multiple sidelink UEs including the first sidelink UE;
determining a cyclic prefix (CP) extension length for transmitting a second sidelink transmission after the first sidelink transmission, a gap duration between the first sidelink transmission and the second sidelink transmission satisfying a listen-before-talk (LBT) gap time threshold;
applying a CP extension having the CP extension length to the second sidelink transmission; and
transmitting, to a second sidelink UE, the second sidelink transmission with the CP extension.
